Dive computers really are targeted at NDL style diving.  The "answers"
they give get further and further from "the truth" the further you take
them into deco.  So the only time I use my computer is when I expect
that I'll only be doing mild decos.  I also always bring a bottom
timer/depth gauge as a backup.  For this style diving, my Aladin uses a
10FSW stop as its first stop and generally it will just keep adding time
to the 10FSW stop for quite a while.  Only once did I push it until it
gave me a 20FSW stop and that stop cleared itself while I was doing my
30FSW stop.  If I'm planning anything more serious than "mild deco", I
leave the Aladin at home (or plan on bending the snot out of it) and
just use tables and a depth gauge/bottom timer.
